A whole new approach to repositioning Cues before Clusters. This
patchset adds a new function CopyAndMoveCuesBeforeClusters to the
Segment class. This function should be called after
Segment::Finalize() to obtain a copy of the same output file with
Cues positioned before the Clusters.
Removing everything else that was added to accomplish the same in
the previous few commits.
Also, adding std:: qualifier to one of the variables in
sample_muxer_metadata which was missed accidentally in the previous
commit.

Replacing "using std::string" with fully qualified namespace on
each occurance of string in sample_muxer_metadata.cc and
webvttparser.cc.
Also fixing a formatting nit in mkvwriteeofreader.cpp
